Effort, catch, and biometric fish data are produced using the Summer Profundal Index Netting (SPIN) methodologies developed by the Ontario Ministry of Natural Resources. Monitoring is generally conducted generally on a five year cycle, with additional sampling as necessary. Data are from Kingsmere Lake, where the majority of the park’s recreational lake trout fishing occurs. This monitoring allows the park to collect data on the size, structure and physical condition of the lake trout population. Because lake trout are long-lived, top-level predators that are sensitive to changes in their environment, they are good indicators of the lake ecosystem overall health.
